I'm having trouble with the syntax of the hdr* matching for creating
ACL's.
I know that my control flow is correct. by changing the acl
defiinition to a simple src ip, i get the desired change of backends.
ie. this will send traffic to img backends (desired)
# acl from_vnsh hdr_sub -i nginx
acl from_vnsh src 208.94.1.44
use_backend varnish if METH_GET ! from_vnsh
default_backend img
this will send it to varnish:
acl from_vnsh hdr_sub -i nginx
# acl from_vnsh src 208.94.1.44
use_backend varnish if METH_GET ! from_vnsh
default_backend img
I think the problem is you shouldn't have the METH_GET in there
use_backend varnish if ! from_vnsh
works for me
oh, i thought there was an implicit AND when two expressions were put
together...which i know is true for the src based acl. i only want
GETs to go to this backend.
Doh! My bad, then you do want that I wasn't sure you could use that directly
in the use_backend or if you had to create an acl based on that "predefine"
